灰色预测

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

This code can be use in raytracing of seismic data.

a frequency modulation code for matlab

相平面分析的matlab程序例子，希望对大家有用(Phase plane analysis matlab program examples, we hope to be useful)

说明：  压缩感知雷达文献，里面包含大量关于压缩感知雷达文章(compressed sensing)

JPEG编码程序（MATLAB） 参考一下吧 (JPEG coding procedures (MATLAB) make reference to it)

space vector pwm inverter implementation using matlab simulation

连接一起的下半部分是传统一次调频系数的仿真，参数如算例所示，上半部分是其改进一次调频系数后的仿真，最后由示波器观测波形的不同。(The lower half of the connection is the simulation of the traditional primary frequency modulation coefficient. The parameters are shown in the example. The first half is the simulation after the improvement of the primary frequency modulation coefficient, and finally the waveform is observed by the oscilloscope.)

This code can be use in fresnelzone of seismic data.
